Detection of broadband squeezed light with a low-noise die-level balanced receiver
Emmily Zaiser, Alessandro Trenti, Dinka Milovančev +3
The generation and detection of squeezed light through spontaneous parametric down-conversion in a nonlinear crystal up to a frequency of 3.5 GHz is presented. We characterize the…

Towards an All-Silicon QKD Transmitter Sourced by a Ge-on-Si Light Emitter
Florian Honz, Nemanja Vokić, Michael Hentschel +3
We demonstrate a novel transmitter concept for quantum key distribution based on the polarization-encoded BB84 protocol, which is sourced by the incoherent light of a forward-biase…
